Doctors and nurses bustle round a patient with a broken leg, when suddenly there is an explosion, darkness, and panicked screams. Now imagine that patient is you.

That is the experience the MSF medical charity is aiming for with a new virtual reality film it is testing and planning to get before decision makers, military commanders, and soldiers on the ground.

The Doctors Without Borders group, known by the French acronym MSF, is launching the film in a bid to counter surging numbers of attacks on medical facilities and medical workers in conflict zones in places like Syria, Yemen, and Afghanistan.

"This kind of tool, the 360-degree (VR film), could be very, very useful in sensitising fighter jet pilots for instance" to what is at stake, explained Francois Delfosse, who heads an MSF project on hospital attacks and protection of medical missions.

And indeed, once you slip on the VR headset and large headphones, you are there, in the middle of a bustling trauma ward, looking down at your outstretched broken leg and waiting for one of the doctors to tend to you.

When the explosion hits, you are stuck in the middle of a darkened corridor, unable to move as bloodied people run screaming past and staff pound frantically on the chest of a person stretched out on the floor in front of you.

If you turn your head, you can see more people running, including an older man, his face caked with dirt and blood, holding what looks like a lifeless baby.

"There was this sense of powerlessness," explained Irene Raciti, of the Red Cross, who volunteered to help test the MSF film on the sidelines of a film festival in Geneva last week focused on human rights.

Sitting in a secluded room with the headset and earphones on, Raciti twisted and turned her head in different directions, at one point gasping and clutching her hands nervously together.

"I was injured, so I couldn't move, and people were running around me, people needed help, and I was powerless," she told AFP after the experience.

She and other test subjects were debriefed by MSF staff afterwards to help determine the effectiveness of the tool before it is presented to politicians and other decision-makers starting on World Humanitarian Day in August.

"MSF asked me to create a traumatizing experience," explained Romain Girard, director of the 360-degree film, which lasts just around two and a half minutes, but feels much longer when you are behind the goggles.

The VR film was created in Geneva, but inspired by media and surveillance footage from a real attacks on hospitals, including the deadly US bombing of an MSF hospital in the northern Afghan city of Kunduz in October 2015 that killed 42 people, including 14 of the charity's staff.

"In that footage, you don't see the bombs fall, but you see the shockwave, the panic and the distress of people there," Girard said, also describing how patients and medical workers in these settings seem to be "transformed into ghosts moving through darkened hallways filled with smoke and dust."
